Please note: Page 1 of Baader's manual for this item states the following: "Please note: There is a protective film on the mirror. We recommend to remove it only after all accessories have been installed at the adjustable T-2 top ring."
However, note that his is no longer correct. There is no such protective film on the mirror in most batches that we receive from Baader.
Various ports – variable work
Telescope auxillary instruments cover a wide range of interests, from a sole eyepiece, via camera use, to high end spectroscopy. Unfortunately every telescope just features one exit port. This causes relentless manual exchange of parts in the dark, causing huge time loss, wear on the parts - and "nerves". And whenever you start controlling your telescope remotely - the single port becomes a painful reality.
Improving workflow, especially during astrophotography is the goal set out for the BFM II. This is not just a simple flip mirror but much more, as there are three ports to be put into action.
General Function of the FlipMirror II Star Diagonal
The BFM II lets you switch between a straight light path for a camera or other measuring instruments and an angled light path, e.g.
for an eyepiece. In addition, a calibration lamp for spectrographs or an Off-Axis-Guider pickoff-prism (that is not affected by the mirror position) can be connected at the AUX-port on the bottom
